Non-invasive Heart Monitoring of Newborn Rodents10


There is a growing awareness that the cardiovascular system is implicated in a wide range of inflammatory and neurological conditions. Many fragile genetically modified mice die at a very young age inexplicably.


™ provides researchers the opportunity to non-invasively monitor the electrocardiogram in newborn laboratory animals from day 1 of life. The design of the LifeSpoon includes a heated array of conductive electrodes in a warm cozy “spoon”, thereby minimizing handling of the pups. Applications include arrhythmia detection, health monitoring, and drug screening in fragile neonates and very young transgenic and knockout animals.

LifeSpoon features:

EzCG Analyses software features:

  • “Quick-connect” to the ECGenie
  • Reusable/disposable footpad electrodes
  • Heating of spoon via USB connection
  • “Spoon” subject back to nest after ECG recording
  • Analysis of ECG from newborn rodents
  • HRV algorithms specific to the developing conduction system
  • Time domain tachogram and frequency domain power spectra
